Configuring the PA-A3
To continue your PA-A3 installation, you must configure the PA-A3 interface. The instructions that follow apply to all supported platforms. Minor differences between the platforms—with Cisco IOS software commands—are noted.
This chapter contains the following sections:
•
Using the EXEC Command Interpreter
•Troubleshooting the PA-A3 Installation and Configuration
•Upgrading Your Boot Flash Image
Using the EXEC Command Interpreter
You modify the configuration of your router through the software command interpreter called the EXEC (also called enable mode). You must enter the privileged level of the EXEC command interpreter with the enable command before you can use the configure command to configure a new interface or change the existing configuration of an interface. The system prompts you for a password if one has been set.
The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket (>). At the console terminal, use the following procedure to enter the privileged level:
Step 1 At the user-level EXEC prompt, enter the enable command. The EXEC prompts you for a privileged-level password as follows:
Router> enable
Password:
Step 2 Enter the password (the password is case sensitive). For security purposes, the password is not displayed.
When you enter the correct password, the system displays the privileged-level system prompt (#):
Router#
PA-A3 Configurations
After you verify that the new PA-A3 is installed correctly (the ENABLED LED goes on), use the privileged-level configure command to configure the new interface. Have the following information available:
•Protocols you plan to route on the new interface
•IP addresses, if you plan to configure the interface for IP routing
•Bridging protocols you plan to use
If you installed a new PA-A3 or if you want to change the configuration of an existing interface, you must enter configuration mode to configure the new interface. If you replaced a PA-A3 that was previously configured, the system recognizes the new interface and brings it up in its existing configuration.
For a summary of the configuration options available and instructions for configuring the interface on a PA-A3, refer to the appropriate configuration publications listed in the "Related Documentation" section.
When an interface is enabled (taken out of shutdown mode) with no additional arguments, the default interface configuration file parameters are functional.
You execute configuration commands from the privileged level of the EXEC command interpreter, which usually requires password access. Contact your system administrator, if necessary, to obtain password access. (See the "Using the EXEC Command Interpreter" section for an explanation of the privileged level of the EXEC.)
This section contains the following subsections:
•Performing a Basic Interface Configuration
•Configuring the PA-A3 for OC-3
•Configuring Classical IP and ARP over ATM
•Classes of Service and Transmit Priority on the PA-A3
Shutting Down an Interface
Before you remove an interface that you will not replace, replace interface cables, or replace port adapters, use the shutdown command to shut down (disable) the interfaces to prevent anomalies when you reinstall the new port adapter or reconfigured port adapter. When you shut down an interface, it is designated administratively down in the show command displays.
Follow these steps to shut down an interface:
Step 1 Enter the privileged level of the EXEC command interpreter (also called enable mode). (See the "Using the EXEC Command Interpreter" section for instructions.)
Step 2 At the privileged-level prompt, enter configuration mode and specify that the console terminal is the source of the configuration subcommands, as follows:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#
Step 3 Shut down the interface by entering the interface command (followed by the interface address of the interface), and then enter the shutdown command. See the "Using the show interfaces Command" section.
When you have finished, press Ctrl-Z—hold down the Control key while you press Z—or enter end or exit to exit configuration mode and return to the EXEC command interpreter.
Note If you need to shut down additional interfaces, enter the interface command (followed by the interface type and the interface address of the interface) for each of the interfaces on your port adapter. Use the no shutdown command to enable the interface.
Step 4 Write the new configuration to NVRAM as follows:
Router# copy running-config startup-config
[OK]
Router#
The system displays an OK message when the configuration has been stored in NVRAM.
Step 5 Verify that new interface is now in the correct state (shut down) using the show interfaces command (followed by the interface type and interface address of the interface) to display the specific interface. See the "Using the show interfaces Command" section.
Step 6 Re-enable the interface by doing the following:
a. Repeat Step 3 to re-enable an interface. Substitute the no shutdown command for the shutdown command.
b. Repeat Step 4 to write the new configuration to memory. Use the copy running-config startup-config command.
c. Repeat Step 5 to verify that the interface is in the correct state. Use the show interfaces command followed by the interface address of the interface.
For descriptions of software configuration commands, refer to the publications listed in the "Related Documentation" section.
Performing a Basic Interface Configuration
Following are instructions for a basic configuration, which include enabling an interface and specifying IP routing. You might also need to enter other configuration subcommands, depending on the requirements for your system configuration and the protocols you plan to route on the interface. For complete descriptions of configuration subcommands and the configuration options available for the interfaces of your port adapter, refer to the appropriate software documentation.
In the following procedure, press the Return key after each step unless otherwise noted. At any time you can exit the privileged level and return to the user level by entering disable at the prompt as follows:
Router# disable
Router>
Step 1 Enter configuration mode and specify that the console terminal is the source of the configuration subcommands, as follows:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#
Step 2 Specify the first interface to configure by entering the interface command, followed by the type of interface and the interface address of the interface you plan to configure. (The command for your port adapter will be specific to the technology of your interface.) The "Using the show interfaces Command" section provides examples.
Step 3 Assign an IP address and subnet mask to the interface (if IP routing is enabled on the system) by using the ip address subcommand, as in the following example:
Router(config-if)# ip address 10.0.0.0 10.255.255.255
Step 4 Add any additional configuration subcommands required to enable routing protocols and set the interface characteristics.
Step 5 Re-enable the interfaces using the no shutdown command. (See the "Shutting Down an Interface" section.)
Step 6 After including all of the configuration subcommands to complete your configuration, press Ctrl-Z—hold down the Control key while you press Z—or enter end or exit to exit configuration mode and return to the EXEC command interpreter prompt.
Step 7 Write the new configuration to NVRAM as follows:
Router# copy running-config startup-config
[OK]
Router#
The system displays an OK message when the configuration has been stored in NVRAM.
Note If you are going to disconnect or reconfigure the ATM interface cable, use the shutdown command before doing so. After reattaching the ATM interface cable, use the no shutdown command to bring up the ATM interface.
Configuring the PA-A3 for T3
To configure the PA-A3 for T3, perform the following tasks in interface configuration mode:
Step 1 Specify an ATM interface configuration. See"Identifying Interface Addresses" section on page 1-21 for the appropriate interface address for your system.
Router# interface atm slot/port or slot/port-adapter/port
Step 2 Set the line build-out length (0 to 50 feet is short and greater than 50 feet is long). Use the no form of this command to return to the default, which is short.
Router(config-if)# lbo {short | long}
Step 3 Select the transmit clock source. This can be internal or derived from the receive clock through use of the no form of the command. By default, the receive clock source is used for the transmit clock.
Router(config-if)# clock internal
Step 4 Enable DS-3 scrambling. Use the no form of the command to restore the default value.
Router(config-if)# DS3-scramble
Step 5 Specify DS-3 framing: m23plcp, cbitplcp, m23adm, or cbitadm. Use the no form of the command to return to the default, which is cbitadm.
Router(config-if)# framing {m23plcp | cbitplcp | m23adm | cbitadm}
Configuring the PA-A3 for E3
To configure the PA-A3 for E3, perform the following tasks in interface configuration mode:
Step 1 Specify an ATM interface configuration. See the "Identifying Interface Addresses" section on page 1-21 for the appropriate interface address for your system.
Router# interface atm slot/port or slot/port-adapter/port
Step 2 Select the transmit clock source. This can be internal or derived from the receive clock through use of the no form of this command. By default, the receive clock source is used for the transmit clock.
Router(config-if)# clock internal
Step 3 Enable E3 scrambling. Use the no form of the command to restore the default value.
Router(config-if)# e3-scramble
Step 4 Specify DS-3 framing: g832adm, g751adm, or g751plcp. Use the no form of the command to return to the default, which is g832adm.
Router(config-if)# framing {g832adm | g751adm | g751plcp}
Configuring the PA-A3 for OC-3
To configure the PA-A3 for OC-3, perform the following tasks in interface configuration mode:
Step 1 Specify an ATM interface configuration. See "Identifying Interface Addresses" section on page 1-21 for the appropriate interface address for your system.
Router# interface atm slot/port or slot/port-adapter/port
Step 2 Select the transmit clock source. This can be internal or derived from the receive clock through use of the no form of this command. By default, the receive clock source is used for the transmit clock.
Router(config-if)# clock internal
Step 3 Specify SONET framing by using the sonet stm-1 command. Use the no form of this command to return to the default, STS-3c framing.
Router(config-if)# sonet stm-1
Note In ATM environments, the key difference between SONET and SDH framing modes is the type of cell transmitted when no user or data cells are available. The ATM forum specifies use of idle cells if unassigned cells are not generated. More specifically, in Synchronous Transport Module-X (STM-X) mode, an ATM interface sends idle cells for cell-rate decoupling. In Synchronous Transport Signal-Xc (STS-Xc) mode, the ATM interface sends unassigned cells for cell-rate decoupling.
Configuring VCs
A virtual circuit (VC) is a point-to-point connection between remote hosts and routers. A VC is established for each ATM end node with which the router communicates. The characteristics of the VC are established when the VC is created and include the following:
•Class of service category:
–Constant bit rate (CBR)
–Non-real-time variable bit rate (nrt-VBR)
–Real-time variable bit rate (rt-VBR)
–Available bit rate (ABR)
–Unspecified bit rate (UBR)
•ATM adaptation layer 5 (AAL5)
•Encapsulation type:
–Logical link control Subnetwork Address Protocol (AAL5SNAP)
–Multiplexer (AAL5MUX)
–Network Layer Protocol ID (AAL5NLPID)
–Integrated Local Management Interface (ILMI)
–Switched Multimegabit Data Service (SMDS)
–ITU/Q.2931 Signaling ATM Adaptation Layer (QSAAL)
–Cisco AUTO PPP over AAL5 (aal5autoppp)
–Cisco PPP over AAL5 (aal5ciscoppp)
Note See the ATM virtual circuit configuration commands in the example output of the "Classes of Service and Transmit Priority on the PA-A3" section.
Each VC supports the following router functions:
•Multiprotocol
•Fast switching of IP packets
•Flow, and Cisco Express Forwarding (CEF) switching of IP packets
•Pseudobroadcast support for multicast packets
By default, CEF switching is enabled on all PA-A3 interfaces. These switching features can be turned off with interface configuration commands. Flow must be explicitly enabled for each interface.
Configuring PVCs
To use a permanent virtual circuit (PVC), configure the PVC in both the router and the ATM switch. PVCs remain active until the circuit is removed from either configuration. When a PVC is configured, all of the configuration options are passed on to the PA-A3. You can write these PVCs into nonvolatile RAM (NVRAM); they are used when the system image is reloaded.
Some ATM switches might have point-to-multipoint PVCs that do the equivalent of broadcasting. If a point-to-multipoint PVC exists, it can be used as the sole broadcast PVC for all multicast requests.
Like Frame Relay, ATM supports two types of interface: point-to-point and multipoint. The one you choose determines whether you need to use the configuration commands that ensure IP to ATM mappings.
To configure a PVC, refer to the following sections:
•Configuring a PVC on a Point-to-Point Subinterface
•Configuring a PVC on a Multipoint Subinterface
Configuring a PVC on a Point-to-Point Subinterface
With point-to-point subinterfaces, each pair of routers has its own subnet. If you put the PVC on a point-to-point subinterface, the router assumes that there is only one point-to-point PVC configured on the subinterface. Therefore, any IP packets with a destination IP address in the same subnet are forwarded on this VC.
To configure a point-to-point PVC, perform the following tasks from configuration mode:
Step 1 Enter interface configuration mode and specify an ATM interface using the interface atm command. Specify the creation of a point-to-point interface by using the point command.
Router(config)# interface atm5/0.200 point
Step 2 You can list the VPI and VCI values using the pvc ? command.
Router(config-if)# pvc ?
<0-255> Enter VPI/VCI value(slash required)
<1-65535> Enter VCI value
WORD Optional handle to refer to this connection
Step 3 Create the PVC. Notice the output telling you that the circuit has been configured on a specific interface.
Router(config-if)# pvc 1/1
Configuring vc 1/1 on interface ATM5/0.200
Router(config-if-atm-vc)#
Note Static map statements are not required for point-to-point subinterfaces.
Configuring a PVC on a Multipoint Subinterface
Multipoint networks generally have three or more routers in the same subnet. If you put the PVC in a point-to-multipoint subinterface or in the main interface (which is multipoint by default), you need to either configure a static mapping or enable inverse Address Resolution Protocol (InARP) for dynamic mapping.
The following output example shows a PVC 2/200 on ATM interface 1/1/0.200. It uses the global default AAL5SNAP encapsulation. The local interface IP address is 2.2.2.1, and the remote interface IP address is 2.2.2.2.
Router# show interfaces atm 1/1/0.200
interface ATM1/1/0.200 multipoint
ip address 2.2.2.1 255.255.255.0
no ip directed-broadcast
pvc 2/200
protocol ip 2.2.2.2 broadcast
InARP is enabled on multipoint links by default. The following example, creates a multipoint subinterface. By using the show atm map command, you can see that InARP builds a dynamic mapping between the Layer 3 IP address and the Layer 2 VPI/VCI:
Router# show atm map
Map list ATM1/1/0.100_ATM_INARP : DYNAMIC
ip 1.1.1.2 maps to VC 19, VPI 2, VCI 100, ATM1/1/0.100
Map list ATM1/1/0.200_ATM_INARP : DYNAMIC
ip 2.2.2.2 maps to VC 20, VPI 2, VCI 200, ATM1/1/0.200
You can check the mapping using the show atm map command. In the following example, you can see the mapping of Layer 3 to Layer 2 addresses is dynamic. Such mapping is dynamic using InARP as illustrated in the previous show atm map command example.
Router# show atm map
Map list ATM1/1/0.100_ATM_INARP : DYNAMIC
ip 1.1.1.2 maps to VC 19, VPI 2, VCI 100, ATM1/1/0.100
Map list ATM1/1/0.200pvc20 : PERMANENT
ip 2.2.2.2 maps to VC 20, VPI 2, VCI 200, ATM1/1/0.200, broadcast
You can use the inarp command to change the frequency of transmitting a new ATM InARP packet in order to reconfirm the mapping:
Router(config-subif)# pvc 2/200
Router(config-if-atm-vc)# inarp ?
<1-60> InARP Frequency in minutes
<cr>
Router(config-if-atm-vc)# inarp 5
Router(config-if-atm-vc)# end
Use the show atm vc command to confirm your configured value:
Router# show atm vc
5d10h: ATMARP:Sending first PVC INARP
5d10h: ATMARP(ATM1/1/0.200)O: INARP_REQ to VCD#20 2/200 for link 7(IP)

Configuring SVCs
ATM switched virtual circuits (SVCs) are created and released dynamically, providing user bandwidth on demand. This service requires a signaling protocol between the router and the switch.
The ATM signaling software provides a method of dynamically establishing, maintaining, and clearing ATM connections at the User-Network Interface (UNI). The ATM signaling software conforms to the ATM Forum UNI 4.0 specification.
In UNI mode, the user is the router, and the network is an ATM switch. This is an important distinction. The Cisco router does not perform ATM-level call routing. Instead, the ATM switch does the ATM call routing, and the router routes packets through the resulting circuit. The router is viewed as the user and the LAN interconnection device at the end of the circuit, and the ATM switch is viewed as the network.
Figure 4-1 illustrates the router position in a basic ATM environment. The router is used primarily to interconnect LANs through an ATM network. Workstation C in Figure 4-1 is connected directly to the destination ATM switch. You can connect not only routers to ATM switches, but also any network device with an ATM interface that conforms to the ATM Forum UNI specification.
Figure 4-1 Basic ATM Environment
To use SVCs, complete the required tasks in the following sections:
•Configuring the PVC That Performs SVC Call Setup
•Configuring the Network Service Access Point Address
For further information on configuring the PA-A3 port adapter for SVCs, see the Wide-Area Networking Configuration Guide.
Configuring the PVC That Performs SVC Call Setup
ATM uses out-of-band signaling. One dedicated PVC exists between the router and the ATM switch, over which all SVC call establishment and call termination requests flow. After the call is established, data transfer occurs over the SVC, from router to router. The signaling that accomplishes the call setup and teardown is called Layer 3 signaling or the Q.2931 protocol.
For out-of-band signaling, a signaling PVC must be configured before any SVCs can be set up. In Figure 4-2, a signaling PVC from the source router to the ATM switch is used to set up two SVCs. This is a fully meshed network; workstations A, B, and C can all communicate with one another.
Figure 4-2 One or More SVCs Require a Signaling PVC
To configure the signaling PVC for all SVC connections, enter the pvc vcd vpi vci qsaal command in interface configuration mode.
Note This signaling PVC can be set up on a major interface only, not on the subinterfaces.
The VPI and VCI values must be configured consistently with the local switch. The standard value of VPI is 0, and the range of VPI values is 0 through 255. The standard value of VCI is 5, and the range of VCI values is 0 through 65535.
Note VCI values 0 through 31 are reserved and do not carry data traffic.
Configuring the Network Service Access Point Address
Every ATM interface involved with signaling must be configured with a network service access point (NSAP) address. The NSAP address is the ATM address of the interface and must be unique across the network.
To configure an NSAP address, complete the tasks in the following sections:
•Configuring the Complete NSAP Address Manually
•Configuring the ESI and Selector Fields
To configure the ESI and Selector fields, you must also configure a PVC to communicate with the switch through ILMI:
Router(config-if)# pvc 0/16 ilmi
The switch then provides the Prefix field of the NSAP address.
Configuring the Complete NSAP Address Manually
When you configure the NSAP address manually, you must enter the entire address in hexadecimal format; that is, each digit entered represents a hexadecimal digit. To represent the complete NSAP address, you must enter 40 hexadecimal digits in the following format:
XX.XXXX.XX.XXXXXX.XXXX.XXXX.XXXX.XXXX.XXXX.XXXX.XX
Note All NSAP addresses must be entered in the dotted hexadecimal format shown, which conforms to the UNI specification.
Because the interface has no default NSAP address, you must configure the NSAP address for SVCs. To set the ATM interface source NSAP address, enter the nsap-address nsap-address command in interface configuration mode.
The following is an example of an NSAP address assigned to ATM interface 4/0 on a Cisco 7200 series, Cisco uBR7200 series, or Cisco 7100 series router:
Router(config)# interface atm 4/0
Router(config-if)# nsap-address AB.CDEF.01.234567.890A.BCDE.F012.3456.7890.1234.12
You can display the ATM address for the interface by executing the show interfaces atm command.
Configuring the ESI and Selector Fields
You can configure the router to get the NSAP address prefix from the switch; however, the switch must be capable of delivering the NSAP address prefix to the router through ILMI, and the router must be configured with a PVC for communication with the switch through ILMI.
To configure the router to get the NSAP prefix from the switch and use locally entered values for the remaining fields of the address, complete the following tasks in interface configuration mode:
Step 1 Specify an ATM interface to configure.
Router(config)# interface atm slot/port or slot/port-adapter/port
Step 2 Enter the ESI and Selector fields of the NSAP address.
Router(config-if)# esi-address esi.selector
In the esi-address command, the esi argument is 6 hexadecimal bytes long (12 digits), and the selector argument is 1 hexadecimal byte long (2 digits).
In the following example on a Cisco 7200 series router, the ESI and Selector field values are assigned, and the ILMI PVC is set up:
Router(config)# interface atm 4/0
Router(config-if)# esi-address 345678901234.12
Configuring Classical IP and ARP over ATM
Cisco implements both the ATM Address Resolution Protocol (ARP) server and ATM ARP client functions described in RFC 1577. RFC 1577 models an ATM network as a logical IP subnetwork on a LAN.
The tasks required to configure classical IP and ARP over ATM depend on whether there are SVCs or PVCs present in the environment. For further information, refer to the Wide-Area Networking Configuration Guide, Release 12.2 at the following URL:
Classes of Service and Transmit Priority on the PA-A3
The transmit priority determines which queued cell is chosen to be transmitted out of an interface during a cell time slot and ensures that real-time ATM service classes, which typically offer more robust QoS and traffic guarantees, have a higher likelihood of access to the next cell time slot. Table 4-1 lists the ATM service classes and their default transmit priorities on the PA-A3.
Note Refer to the Feature Module documentation and Technical Tips on Cisco.com for detailed information about classes of service, configuration features, and the Cisco IOS releases that the support specific features.
Transmit priority 0 is reserved for control traffic such as OAM and signaling.
You can use the transmit-priority command in VC configuration mode to change the priority value. The following example shows a customized prioritization scheme with the transmit priority value of a VC changed from 4 to 2.
Step 1 First, view the characteristics of the existing configuration using the show atm vc {vcd#} command. Note how the router has assigned a default transmit priority value of 5 to the UBR PVC:
Router# show atm vc 2
ATM5/0: VCD: 2, VPI: 1, VCI: 100
UBR, PeakRate: 10000
AAL5-LLC/SNAP, etype:0x0, Flags: 0x20, VCmode: 0x0
OAM frequency: 0 second(s)
PA TxRingLimit: 0 paritcles
PA Rx Limit: 0 particles
InARP frequency: 15 minute(s)
Transmit priority 5
InPkts: 0, OutPkts: 0, InBytes: 0, OutBytes: 0
InPRoc: 0, OutPRoc: 0, Broadcasts: 0
InPktsDrops: 0, OutPktDrops: 0
CrcErrors: 0, SarTimeOuts: 0. OverSizedSDUs: 0
OAM cells received: 0
OAM cells sent:0
Status: ACTIVE
Step 2 Next, customize the transmit priority value from VC configuration mode.
Router(config)# interface atm 5/0
Router(config-if)# pvc x/100
Router(config-if-atm-vc)# transmit-priority 2
Step 3 The final action is to confirm your settings. Note how the router indicates the changed transmit priority level. It is now at level 2.
Router# show atm vc 2
ATM5/0: VCD: 2, VPI: 1, VCI: 100
UBR, PeakRate: 10000
AAL5-LLC/SNAP, etype:0x0, Flags: 0x20, VCmode: 0x0
OAM frequency: 0 second(s)
PA TxRingLimit: 0 paritcles
PA Rx Limit: 0 particles
InARP frequency: 15 minute(s)
Transmit priority 2
InPkts: 0, OutPkts: 0, InBytes: 0, OutBytes: 0
InPRoc: 0, OutPRoc: 0, Broadcasts: 0
InPktsDrops: 0, OutPktDrops: 0
CrcErrors: 0, SarTimeOuts: 0. OverSizedSDUs: 0
OAM cells received: 0
OAM cells sent:0
Status: ACTIVE
Customizing the PA-A3
You can customize the PA-A3. The features you can customize have default values that will probably suit your environment and not need to be changed. However, you might need to enter configuration commands, depending on the requirements for your system configuration and the protocols you plan to route on the interface. Perform the tasks in the following sections if you need to customize the PA-A3:
•Configuring an ATM Interface for Local Loopback
•Configuring an ATM Interface for External Loopback
Note For the commands that follow, you need to be in interface configuration mode. To enter interface configuration mode, use the interface atm command, followed by the interface address of the ATM interface you plan to configure.
Setting the MTU Size
Each ATM interface has a default maximum packet size or maximum transmission unit (MTU) size. On the PA-A3, this number defaults to 4470 bytes, the range being 64 through 9188 bytes. To set the maximum MTU size, enter the following command in interface configuration mode:
Router(config-if)# mtu bytes
Note This command is documented in the Cisco IOS Configuration Fundamentals Command Reference, Release 12.2 at the following URL:
http://www.cisco.com/en/US/products/sw/iosswrel/ps1835/products_command_reference_book09186a00800811e0.html
Configuring an ATM Interface for Local Loopback
To configure an ATM interface for local loopback (useful for checking that the PA-A3 is working by looping the transmit data back to the receive data), use the following command:
Router(config-if)# loopback diagnostic
Router(config-if)# loopback diagnostic
The no form of the command turns off local loopback:
Router(config-if)# no loopback diagnostic
Configuring an ATM Interface for External Loopback
To configure an ATM interface for external loopback (useful for checking that the PA-A3 is working by looping the receive data back to the transmit data), use the following command:
Router(config-if)# loopback line
The no form of the command turns off external loopback:
Router(config-if)# no loopback line
Checking the Configuration
After configuring the interface, use the show commands to display the status of the new interface or all interfaces, and use the ping and loopback commands to check connectivity. This section includes the following subsections:
•Using show Commands to Verify the New Interface Status
•Using the ping Command to Verify Network Connectivity
Using show Commands to Verify the New Interface Status
This section demonstrates how you can use the show commands to verify that new interfaces are configured and operating correctly and that the port adapter appears in them correctly. Sample displays of the output of selected show commands appear in the sections that follow.
If an interface is shut down and you configured it as up, or if the displays indicate that the hardware is not functioning properly, ensure that the interface is properly connected and terminated. If you still have problems bringing up the interface, contact a service representative for assistance. This section includes the following subsections:
•Using the show version or show hardware Commands
•Using the show interfaces Command
Using the show version or show hardware Commands
Display the configuration of the system hardware, the number of each interface type installed, the Cisco IOS software version, the names and sources of configuration files, and the boot images, using the show version (or show hardware) command.
Note The outputs that appear in this document may not match the output you receive when running these commands. The outputs in this document are examples only.
The following sections provide platform-specific output examples using the show version command:

You have completed a basic interface configuration. Depending on your version of the PA-A3, you might need to specify configuration for T3 (DS-3), E3, or OC-3c.
Note To verify your network connectivity, see the "Using the ping Command to Verify Network Connectivity" section, for a brief description of the ping command.
For a description of the interface subcommands and configuration options available for ATM interfaces, refer to the "Related Documentation" section.
Using the ping Command to Verify Network Connectivity
Using the ping command, you can verify that an interface port is functioning properly. This section provides a brief description of this command.
The ping command sends echo request packets out to a remote device at an IP address that you specify. After sending an echo request, the system waits a specified time for the remote device to reply. Each echo reply is displayed as an exclamation point (!) on the console terminal; each request that is not returned before the specified timeout is displayed as a period (.). A series of exclamation points (!!!!!) indicates a good connection; a series of periods (.....) or the messages [timed out] or [failed] indicate a bad connection.
Following is an example of a successful ping command to a remote server with the address 10.0.0.10:
Router# ping 10.0.0.10 <Return>
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echoes to 10.0.0.10, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/15/64 ms
Router#
If the connection fails, verify that you have the correct IP address for the destination and that the device is active (powered on), and repeat the ping command.
Using loopback Commands
The loopback command places an interface in loopback mode, which enables test packets that are generated from the ping command to loop through a remote device. If the packets complete the loop, the connection is good. If not, you can isolate a fault to the remote device in the path of the loopback test.
The loopback diagnostic command on an ATM interface of a Cisco router causes traffic going out of the interface to come back to the router.
If loopback is not set on the ATM interface, traffic will not be looped back. Traffic will go out but will not return. Apply the loopback diagnostic command, and then use the show interfaces atm command to show that loopback is indeed set:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# interface atm 1/0
Router(config-if)# loopback diagnostic
Router(config-if)# atm clock internal
Router(config-if)# ^Z
Router# show interface atm 1/0

Note To ensure proper clocking, set the router as the clock source by specifying the atm clock internal command in the main interface configuration.
The loopback line command on an ATM interface of a Cisco router causes incoming traffic to be sent back to the network. Apply the loopback line command, and then use the show interfaces atm command to show that loopback is indeed set:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.

The following topics are covered within this section:
PA-A3 Statistics
The PA-A3 maintains a count of certain errors and tracks the ATM facility performance. In addition to keeping a count of these errors, the PA-A3 also takes snapshots of the last VCI/VPI that caused the error. Each PA-A3 error counter is made up of 16 bits. Errors counted include the following:
•Cyclic Redundancy Check (CRC) errors
•Giants received
•No buffers available
•Framing errors
•Application layer or physical layer errors
•Packet timeout errors on receive
The PA-A3 provides port adapter-specific error statistics through the show interfaces atm command.
Note For examples of the show interfaces atm command for all supported platforms, see the "Using the show interfaces Command" section.
The show controllers atm command displays the ATM framing information and ATM facility performance statistics. The statistics report section includes up to 96 15-minute interval reports, as well as the current interval level. Only those intervals with non-zero data are displayed.

Using the debug atm Commands
The following debug commands help to solve ATM network problems:
•Use the debug atm packet command to create a dump of all protocol packets. The command displays the contents of the SNAP/NLPID/SMDS header followed by the first 40 bytes of a packet in hexadecimal format.
Router# debug atm packet
•Use the debug atm errors command to display errors. The command displays information from all detected ATM errors. This includes such errors as encapsulation failures and errors during ATM configuration.
Router# debug atm errors
•Use the debug atm events command to display ATM events. The command displays event changes to the PA-A3; reset, VC configurations, and PA-A3 configurations are displayed.
Router# debug atm events
•Use the debug atm oam command to display information about OAM cells. The command displays the contents of OAM cells as they arrive from the network.
Router# debug atm oam
•Use the no debug command to turn off debugging after using a debug command.
Router# no debug atm packet
Displaying ATM Information
You can use show atm commands to display the current state of the ATM network and the connected VCs.
•Use the show atm vc [vcd] command to show current VCs and traffic information. Specifying a VCD displays specific information about that VCD.
Router# show atm vc [vcd]
•Use the show atm interfaces command to show current information about an ATM interface. The command displays ATM-specific information about an interface.
Router# show atm interfaces
•Use the show atm traffic command to show current ATM traffic. The command displays global information about traffic to and from all ATM networks connected to the router.
Router# show atm traffic
•Use the show atm map command to show the current ATM mapping. The command displays the active list of ATM static maps to remote hosts on an ATM network.
Router# show atm map
•Use the show sscop command to display SSCOP details for the ATM interface.
Router# show sscop
•Use the show version command to display the configuration of the system hardware (the number of each interface processor type installed), the software version, the names and sources of configuration files, and the boot images.
Note For examples of the show version command for all supported platforms, see the "Using the show interfaces Command" section.

ATM Configuration
Cisco IOS Release 11.3T introduced the ATM VC command mode, which, in turn, introduced several new ATM commands that allow you to configure ATM parameters more easily. The new VC configuration mode uses protocol ip and other statements (replace ip with ipx, decnet, and so on) to configure static mappings. The protocol statement takes the place of the map-list and map-group statements used in versions prior to Cisco IOS Release 11.3T.
The following example shows how to create a PVC AAL5SNAP on a Cisco IOS version earlier than Cisco IOS Release 11.3T. The interface is at IP address 10.0.0.1, with 10.0.0.2 at the other end of the connection.
First Router

ip address 10.0.0.1 255.0.0.0
no keepalive
map-group atm-in

Upgrading Your Boot Flash Image
The boot image contains a subset of the Cisco IOS software. This image is used to perform network booting or to load Cisco IOS images onto the router. This image is also used if the system cannot find a valid system image. When you upgrade your Cisco IOS software to the minimum required software release, we recommend that you also upgrade your boot image. To upgrade your boot image, you can copy the new boot image from a network server to flash memory on your router.
To copy a boot image from a Trivial File Transfer Protocol (TFTP) server to flash memory, complete the following procedure:
Step 1 Enter configuration mode.
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#
Step 2 Display and note the exact spelling of the system image filename in flash memory.
Router(config)# show flash all
Step 3 Make a backup copy of the current boot image.
Router(config)# copy flash tftp
Step 4 Copy a boot image to flash memory.
Router(config)# copy tftp flash
Step 5 When prompted, enter the IP address or domain name of the server.
Router(config)# ip-address or name
For further information, such as how to set up the TFTP server, refer to the Cisco IOS Configuration Fundamentals Configuration Guide, Release 12.2 at the following URL:
Port Adapter Error Messages
All of the PA-A3 receive buffers are allocated from static random-access memory (SRAM). As a result, during bootup, if the PA-A3 cannot find enough contiguous SRAM for its use, the system stops bringing up the PA-A3 and displays an error message such as the following:
%ATMPA-3-PCIMEMNOTENOUGH: Not Enough PCI memory (0x19874) to support ATM PA on bay 5
